rmpage – A package to help change page layout parameters in LaTeX

The pack­age lets you change page lay­out pa­ram­e­ters in small steps
over a range of val­ues us­ing op­tions. It can set
\tex­twidth ap­pro­pri­ately for the main fount, and en­sure
that the text fits in­side the print­able area of a printer. An
rm­page-for­mat­ted doc­u­ment can be type­set iden­ti­cally with­out
rm­page af­ter a sin­gle cut and paste op­er­a­tion. Lo­cal
con­fig­u­ra­tion can set de­faults: for all doc­u­ments; and by class,
by printer, and by pa­per size. The
ge­om­e­try pack­age is bet­ter if you
want to set page lay­out pa­ram­e­ters to par­tic­u­lar mea­sure­ments.
